  1. (+) = positive test; (−) = negative test
  2. Weight and yield of Oroxylum indicum was calculated from a 1.0 kg extraction of raw material. aThe TPC and TFC were derived from calibration curves using the relevant standard and based on dry weight of Oroxylum indicum. The data are expressed as the mean ± SEM of three independent experiments performed in triplicate (n = 9)
